how do you write ionic equations, i mean i looked it up in the book but i didnt get it, can anyone explain it to me please. in an easy manner, because im dumb.
Have you studied it from Chemistry Matters? That explains it well imo.

I barely know you, you barely know me
yeah mairee itnee auqat kahanLol, not you.
I confused your name with him. Nevermind. xD
Mohammad Farzanullah got a world distinction in maths. Not you.
we all know thtyeah mairee itnee auqat kahan
just jking.....yeah mairee itnee auqat kahan
r u giving papers this year or not.........?Assume Y has a Voltage of 200 V so From Y the electrons flow to plate 2 .ok? that you can undertstand but the Plate 1 will have 0 voltage against it so it will attract the electron toward itself i.e point X
He's in A1.r u giving papers this year or not.........?
oh....cool stuff....He's in A1.
i saw it in a past paper for 1o marks,,,,,,,,
They must have been vintage past papersi saw it in a past paper for 1o marks,,,,,,,,

These points can be made upto 10 marks by explaining each briefly.
would u mind explaining briefly.....These points can be made upto 10 marks by explaining each briefly.
it was in 2006...and to check for cholorplast presence...i guess....They must have been vintage past papers
exploded diper here you go!
thx manexploded diper here you go!
- First add a few drops of water or solution on the microscope slide to avoid dryness and wilting
- Take a small piece of onion and using forceps (tweezers), peel off the membrane from the underside (the rough side).
- Lay the membrane flat on the surface of the slide
- Using a pin, lower a thin glass cover slip or cover glass onto the slide. Make sure there are no air bubbles
- Looking from the side (NOT through the eyepiece), lower the tube using the coarse focus knob until the end of the objective lens is just above the cover glass. Do this carefully so as not to crack the cover glass (and possibly damage the objective lens)
- Now look through the eyepiece and turn ONLY the smaller, fine focusing knob to move the optical tube upwards until an image comes into focus. The cells should look something like lizard skin.
- Swap the objective lens for a higher powered one so that you can see the cells at greater magnification. You should be able to make out a nucleus in each cell.
- Repeat the process after adding a dye solution (iodine or methylene blue). Be very careful; these dyes can stain your skin and clothes.#copied. You may add that the section should be as thin as possible for clearer observation under the microscope.
The test tube must be dry because any water or chemicals in the test tube may affect the experiment and consequently the resultbefore statring ethanol emulsion test y do u make sure tht the ethanol test tube is dry...
and y is ethanol added before water....
